prestige aps-787n, 07 hyundai sonata

Which Diode should i get Radioshack only have 1n4001 , 1n4003, 1n4004.

Ok so the Guide says install a relay for channel 3 or even ch5  to open the trunk is this necessary for my car?

Thanks on the info of the Auto lights didnt know that i always run them on auto. I could select + or - for the lights on the unit.  Is there a wire near the light switch thats + that ties both side of the car lights? because according to the cars wire diagrams  two relays needed to tie both sides of the car lights.

BROWN / black left side and GREEN/ black side right founded at the drivers kick panel harness to rear of car.

It should not relock on its own.   When the keyless is used on an 07 Sonata, the BCM receives an RF signal from the key fob to lock or unlock the doors; if unlock is received, and no doors are opened,  the system rearms and relocks after 30 seconds. 

When you wire the APS 787, You would use the unlock/disarm signal that is generated when the door is unlocked using the door key cylinder (factory disarm/unlock, orange wire in the drivers kick panel, also the brown position sense wire same DKP area, common connection for the banded end of 2 diodes to the green unlock signal of the APS 787, one diode to the orange unlock/disarm, one to the position sense).   This does not relock the vehicle.
